Engine and Emissions Technology

C18 with ACERT Technology

Reduce emissions without sacrificing performance – the C18 ACERT engine in the new D9T Waste Handler meets Tier 4 Final and Stage IV emission standards and will continue to work productively and economically in tough landfill applications. The previous D9T Waste Handler model is still available in less regulated countries and can achieve emissions levels equivalent to Tier 2/Stage II and Tier 3/Stage IIIA standards.

Cat NOx Reduction System (NRS)*

The Cat NOx Reduction System captures and cools a small quantity of exhaust gas, then routes it into the combustion chamber where it drives down combustion temperatures and reduces NOx emissions.

Diesel Particulate Filter (DPF)*

The Diesel Particulate Filter can provide a particulate reduction of greater than 90%. It filters soot from the exhaust. Soot is then removed through the regeneration process automatically or manually.

Selective Catalytic Reduction (SCR)*

The Selective Catalytic Reduction system can provide a NOx reduction of greater than 90%. SCR operation is transparent to the operator during operation. The urea solution Diesel Exhaust Fluid (DEF), is pumped from DEF tank and is sprayed into the exhaust stream. The DEF reacts with the SCR catalyst to reduce NOx.

Diesel Exhaust Fluid (DEF)*

Diesel Exhaust Fluid is a liquid that is injected into the exhaust system of engines equipped with Selective Catalytic Reduction (SCR) systems. On the D9T the DEF tank is located on the left hand fender enclosure next to the fuel tank. Diesel Exhaust Fluid that meets ISO 22241 specifications is required.

Aluminum Bar Plate Radiator – 6 Fins per Inch (fpi)

Air-to-Air Aftercooling

Air-to-air aftercooling on the D9T cools hot, compressed air coming out of the turbocharger providing cooler and denser air for the air intake system. Bringing more cool air into the engine increases power generation, lowers emissions, and improves fuel efficiency.

Air to Oil Hydraulic Cooler

Helping to save on repair and maintenance costs, the air to oil hydraulic cooler helps extend component life by reducing hydraulic oil temperatures. The core is built using the same rugged aluminum bar plate design as the engine radiator.

Closed Circuit Hydraulically Variable, Demand Fan

Customers experience increases in production and fuel economy as well as reductions in fan noise and engine overcooling with the closed circuit hydraulically variable demand fan. The demand fan changes speed to match ambient conditions. In cooler environments, the fan turns at a slower speed; consuming only the power required to cool the tractor systems, providing more power to the tracks to help you lower your cost per unit of material moved.

Power Train

Power Train

The power shift transmission and differential steering work with the C18 ACERT engine to deliver the outstanding power, productive performance and reliability expected from Cat Large Dozers. Differential steering maintains full power to both tracks to provide best-in-class turning with a loaded blade. When one track speeds up, the other slows down an equal amount. Maneuverability – especially with large blade loads – is improved, as well as cycle times in some applications. Greater load capacity, power and speed control are possible in soft underfoot conditions on steep slopes.

High Availability is Key

Major power train components are modular in design, so being able to quickly remove and reinstall a new pre-tested component gives you the ability to keep the dozer up and running and producing.

Structure

Mainframe Strength – Built to Last

Helping you get more done with maximum availability, the D9T's durable design makes repair and maintenance easy. Customers can rebuild these tractors several times using the same frame with only minor repairs. With unparalleled support from Cat dealers it is not unusual for a Cat large dozer to log more than 100,000 hours.

The D9T mainframes are built to absorb high impact shock loads and twisting forces encountered during severe dozing and ripping applications.

The main case, equalizer bar saddle, and front cross member are heavy duty steel castings incorporated into highly loaded areas of the mainframe to improve stress distribution for improved durability.

Top and bottom rails are made from continuous rolled sections to eliminate welds and machining, providing superior mainframe durability.

The main case elevates the final drives well above the ground level work area to protect them from impact loads, abrasion and contaminants.

Undercarriage

Undercarriage

The D9T Waste Handler features the Cat elevated sprocket and fully suspended undercarriage design that isolates final drives, axles, and steering components from harsh impacts – resulting in a smoother, more comfortable ride in addition to improved production and longer component life. Every single piece of rolling stock (idlers or rollers) that is in contact with ground has the ability to move up and down. This oscillation allows the undercarriage to envelop obstacles in landfills to keep the track in contact with the ground for superior traction and performance. The undercarriage is designed for easy clean-out, and a modular design aids serviceability to help reduce maintenance costs.

Debris Resistant Features

Cat Waste Handlers are designed with guarding and seals that are critical to the life of your investment and keeping the D9T productive in this application.

Hinged cleanout slot covers offer quick access to the front side of the radiator cores for cleaning.

Engine enclosures have perforated hood and side panels to help prevent airborne debris from entering the engine compartment and helps reduce radiator plugging.

Turbine Engine Precleaner and Dust Ejector delivers clean air and provides longer filter life. The intake air is spun by a flow driven impeller. Debris stratifies along the outer wall and is ejected back into the environment, allowing only precleaned air to continue to the engine's air filter.

High-capacity ducted alternator provides additional power required for electrical accessories. Ducting is provided that helps prevent debris from entering into the alternator for longer life.

Sealed Bottom Guards* help protect against contact damage and help keep debris out of vital machine compartments.

Clamshell Guards* are designed to optimize performance in waste handling applications. Using clamshell guards with inspection covers will protect the final drive seal from damage due to winding of wire, nylon strapping, fishing line, etc.

Optional Waste Handling Attachments

A number of optional features are recommended to help customers get optimal performance from their D9T Waste Handler.

Cat landfill blades increase the dozing capacity in trash and help prevent material from spilling over the blade and entering the radiator.

Front striker bars angled design helps prevent debris from riding up the track during tractor reversal to prevent material from damaging the fenders or fuel and hydraulic tanks.

Rear striker bar includes a striker bar, storage box, drawbar, three slab counterweight, fast fuel system, and transmission guard. The bar is used to knock material off of the tracks during forward operation to prevent material from packing between the track and fender.

Trapezoidal hole track shoes help extends service life by reducing refuse packing within the track. The trapezoidal hole design allows the sprocket to punch out most dirt and debris help extend track pin life.

Powered cab air precleaner includes an additional centrifugal precleaner to separate excess dust particles before the air enters the cab fresh air filter extending filter life.

Operator Station

The D9T's cab design provides ergonomic controls, intuitive monitoring systems, and enhanced visibility. All of the new features within the D9T operator station provide an industry leading operator environment that helps contribute to high levels of productivity, efficiency, and comfort.

Implement and Steering Controls

The D9T utilizes electro-hydraulically controlled differential steering, which helps keep power to both tracks for constant centerline velocity for higher productivity in applications with a lot of turning. Also allows for counter rotation of tracks. This steering system combines the direction and degree of turns, forward-reverse shifting, and gear selection in a single control handle, to enhance operator comfort and help reduce fatigue.

A low-effort electronic dozer control handle gives the operator complete control of all dozer functions with one hand.

Wide Panoramic View

For enhanced safety and production, the operator station offers an exceptional viewing area.

The tapered hood, notched fuel tank, and narrow ripper carriage (if equipped) gives the operator a clear line of sight to front and rear work areas.

Integrated Technologies

Cat Grade Control 3D

Cat Grade Control for dozers is an integrated electronic system that works in landfill applications to ensure the correct amount of material is moved. This helps conserve valuable airspace and cover soil with reduced stakes and crews. The system uses dual ROPS mounted Global Navigation Satellite System (GNSS) antennas and in-cylinder position sensors to provide precise positioning of the cutting edge. This eliminates the need for masts and cables on the blade and improves visibility for the operator. As compared to traditional aftermarket externally mounted sensors, the Cat Grade Control sensors are protected from the harsh working environments in the landfill. Additionally, Cat Grade Control 3D permits the identification of site specific storage areas such as hazardous waste, medical, industrial, organic, and other materials which require special handling or a record of their placement.
